How Much Does Air Duct Replacement Cost in 2025?
If you have noticed uneven airflow, higher energy bills, or dust building up around your home, your air ducts could be the culprit.

But how much does air duct replacement cost in 2025?
The answer depends on several factors, including the size of your home, the materials used, and labor rates in your area. In this guide, we will explore everything you need to know about

Average Air Duct Replacement Cost in 2025
In 2025, the average air duct replacement cost ranges between $3,000 and $8,000 for a standard single-family home. On average, most homeowners spend about $5,500 for a complete replacement. However, the actual cost can fall on the lower or higher end of that range depending on the complexity of the project.
For a small home between 1,000 and 1,500 square feet, homeowners typically pay between $2,500 and $4,500. A medium-sized home between 1,500 and 2,500 square feet may cost between $4,500 and $7,000. Larger homes over 2,500 square feet often cost $7,000 to $12,000 for a full replacement.
If you want a quick rule of thumb, the cost of ductwork is often calculated by the linear foot, ranging from $25 to $55. The total expense depends on the amount of ducting needed and how difficult it is to access and install.
Key Factors That Affect Air Duct Replacement Cost
There is no one-size-fits-all answer for how much air duct replacement will cost. Several variables determine how much you will spend. Here are the most important ones to consider.
Size of Your Home
The larger your home, the more ductwork is required to circulate air properly. Bigger homes require more materials, more time, and more labor, which increases the overall project cost.
Type of Duct Material
Different types of duct materials have different price points and performance benefits.
- Flexible ductwork is the most affordable and easier to install, but it is not as durable as other options.
- Sheet metal ducts are stronger and longer-lasting but come at a higher upfront cost.
- Fiberglass-lined ducts offer soundproofing but may require more maintenance over time.
Labor Costs
Labor accounts for a significant portion of duct replacement costs, often between 30 and 50 percent of the total. Complex layouts with multiple floors, attics, or crawl spaces will increase labor costs compared to a simple, open layout.
Accessibility
If your ducts are located in hard-to-reach spaces, such as a narrow attic or a tight crawl space, the project may require more time and effort, which raises the final price.
Extra Services
Many duct replacement projects also involve additional services. These can include removing and disposing of old ducts, sealing and insulating new ducts, or safely removing asbestos if your home is older. These extra services can add anywhere from $500 to $2,000 to your final bill.
Repair vs. Replacement: Which Is Right for You?
Sometimes, full replacement is not necessary. If your ductwork is relatively new and only has a few damaged areas, repairs may be enough. Duct repair in 2025 typically costs between $500 and $2,500. Duct sealing, which helps close small leaks and improve energy efficiency, usually costs between $1,000 and $3,000.
If your duct system is more than 15 to 20 years old, however, a full replacement is often the smarter investment. New ducts provide improved airflow, reduced energy waste, and better indoor air quality. While repairs may seem less expensive upfront, replacing old ducts can save you money over time by lowering energy bills and reducing HVAC strain.
Tips to Save Money on Air Duct Replacement
Replacing air ducts can be a big expense, but there are ways to keep the cost manageable.
- Get multiple quotes. Comparing estimates from different HVAC contractors can help you find a fair price.
- Combine projects. If you are replacing your HVAC system soon, bundle duct replacement at the same time to save on labor.
- Look for rebates. Some energy providers and state programs offer rebates for energy-efficient upgrades.
- Choose materials wisely. While flexible ducts may save money upfront, sheet metal ducts last longer and may be more cost-effective in the long run.
